República Mista (English: Mixed Republic) is the title of a seven-volume legal-political treatise from the Spanish Golden Age by Tomás Fernández de Medrano, a Navarrese-Castilian nobleman, lord and divisero of Valdeosera, secretary of the holy chapters and assemblies of Castile, knight of the Order of St. John, philosopher, jurist, magistrate, theologian, royal counselor, and secretary of state and war to the Dukes of Savoy. While only the initial part was published, volume one was brought to light by Medrano's son Juan Fernández de Medrano y Sandoval, and published by Juan Flamenco in Madrid on the royal press in 1602 by decree of King Philip III. Composed in Early Modern Spanish and Latin, República Mista codified a doctrine of governance grounded in a mixed republic combining monarchy, aristocracy, and timocracy. The first volume is structured around the foundational precepts of religion, obedience, and justice.

Situated within the mirrors for princes tradition, República Mista codifies the moral and juridical responsibilities of rulers, magistrates, and subjects, and is noted for its formal treatment of delegated authority in early modern Spain. Fray Juan de Salazar's 1617 treatise explicitly cited the doctrine codified by Medrano in the República Mista (1602) to define the Spanish monarchy as guided by virtue and reason, yet bound by divine and natural law.

Without naming him, the República Mista aligns with the anti-Machiavellian tradition by rejecting the view that religion functions only as a political instrument. For Medrano, religion is the foundation of moral order and the precondition for legitimate governance.
